Answer / sushil

for ease and precision in transformation of voltage, ratio
should be in the multiple of form factor 1.11.

Answer / medoo

the same answer

Answer / shilpa

plz...dont give stupid answers lyk the previous one.

its becoz of the form factor which is 1.11 of sinusoidal
wave as transformer involves pure sinusoidal ac supply.

Answer / madhav

form factor of sinusoidal wave=rms/avg..its value should be
1.11. so rms=1.1*avg. for example..10kV*1.1=11kV....

Answer / akshay

becoz generated EMF=4.44f*N*flux Volts, so the vale of
NFand fluz will be multiply by 4.44 so its look like in the
form of 11,22,33 etc

why ground clearance of EHV line is more than HV line??

I have connected 04nos. earthings to a transformer through 04nos. earthing pits seperately. 02nos. earthings are connected to T/F body, and 02nos. earthings are connected to T/F neutral.T/F capacity is 2000KVA, 11KV/415V. But after completing of 02 years successful operation ,we are facing following problems- 1. CT/PT occured blast one time 2. HT cable box occured blast two times 3. One body earthing strip and one neutral earthing strip of transformer are overlapping at some places. Whenever these two strips are pressed at overlapped points, they made spark. What is the reason of spark? Please explain the reason & rectification of above problems

Dear Friends, I have a 500KVA transformer supplying whole factory having 3 phase and single phase mixed loads. Power room has ammeters connected via CTs for individual phase. Now I know that readings shown on meter for each phase say R,Y and B are line currents. But when I want to know the total on transformer do I need to add the currents of all three phases readings shown on meter or value for anyone phase will give me the correct power load on transformer for that point of time. 2. If ammeter shows unbalanced readings for R,Y, B phases say 150, 250 and 300 respectively so can I assume that 150A i.e average of 3 will be the 3phase load currents and remaining will be 1phase currents. Please clarify my doubt.
